### Mechanical Engineering Problem: Determining Forces and Acceleration of a Constrained Frame#### Problem Statement:The frame is made from a uniform rod which has a mass \( \rho \) per unit length. A smooth recessed slot constrains the small rollers at \( A \) and \( B \) to travel horizontally. Force \( P \) is applied to the frame through a cable attached to an adjustable collar \( C \). Determine the magnitudes and directions of the normal forces which act on the rollers if:- \( (a) \, h = 0.25L \)- \( (b) \, h = 0.50L \)- \( (c) \, h = 0.81L \)where \( h \) is the vertical distance of the collar from the bottom roller, and \( L \) is the length of the sides of the square frame.The forces will be positive if up, negative if down. Evaluate your results for:- \( \rho = 2.5 \, \text{kg/m} \),- \( L = 510 \, \text{mm} \),- \( P = 43 \, \text{N} \).What is the acceleration of the frame in each case?#### Diagram Explanation:There is an illustration of the frame as described:- The frame forms a square with side length \( L \).- There are small rollers at points \( A \) and \( B \) at the bottom vertices of the square.- A cable applies force \( P \) horizontally to the frame through a collar \( C \) located a height \( h \) above the bottom roller \( B \).#### Answers:To solve this problem, you need to determine the values for:- Normal force \( N_A \) at roller \( A \),- Normal force \( N_B \) at roller \( B \),- Acceleration \( a \) of the frame in each scenario.##### When \( h = 0.25L \):- \(N_A = \) [Your calculated value]- \(N_B = \) [Your calculated value]- Acceleration \( a = \) [Your calculated value] m/s\(^2\)##### When \( h = 0.50L \):- \(N_A = \) [Your calculated value]- \(N_B = \) [Your calculated value]- Acc

The frame is made from uniform rod which has a mass p per unit length. A smooth recessed slot constrains the small rollers at A and B to travel horizontally. Force P is applied to the frame through a cable attached to an adjustable collar C. Determine the magnitudes and directions of the normal forces which act on the rollers if (a) h = 0.25L, (b) h = 0.50L, and (c) h - 0.81L. The forces will be positive if up, negative if down. Evaluate your results for p = 2.5 kg/m, L = 510 mm, and P = 43 N. What is the acceleration of the frame in each case?
